Hi, my name's Brandon Howell. I'm a product marketing engineer here at Intersil, and I'm at the APEC 2014 Conference. Here I'm showing the ISL8216M. It's a 10 to 80 volt input range, 2.5 volt to 30 volt output four amp power module. So, the power module integrates the controller, the mosfets, the inductor all in one package. It only requires input and output capacitance for a full DC Supply.
So, let me explain the setup we have here I have an ISL8216 demo board. With an oscilloscope I'm looking both the input voltage and the output voltage. For the input it's a 48 volt DC power supply and then on the output it's a 12 volt out and on the scope I have it AC coupled. So I'm showing the v-out ripple for this application. So we have minimal capacitance on the board and were seeing less than 30 millivolts peak-to-peak, so it's a very quiet 12 volt rail, minimal output voltage ripple.
So, the benefit of a module has the controller, it has the mosfets, it has the inductor all integrated into one package. So for time to market, it's very fast time to market. Not a lot of design for the end user. It's really just, put the module down, add input/output capacitance, and you've got a full solution.
So the ISL8216M has a 10 volt to 80 volt input range an adjustable 2.5 volt to 30 volt output range, a max current of four amps. The regulation accuracy is plus or minus one percent over temperature. The switching frequency can be adjusted from 200 kilohertz to 600 kilohertz. It has a frequency sync so the switching frequency can sync to an external clock as a power guard and an integrated soft start.
